Senior Software Engineer (P 2 ) – Full Stack (Java, Spring Boot, React)

Location: Bangaluru, India (Hybrid) Experience: 4 – 7 years Domain: Healthcare Technology (Oncology / Clinical Platforms)

We are looking for a Senior Full Stack Software Engineer to design, build, and operate scalable, mission-critical healthcare applications. This is a backend-first full-stack role (~70% backend / 30% frontend) where you will primarily work on Java + Spring Boot microservices , while contributing to React-based UI layers to deliver complete end-to-end features. You will also operate in an AI-first engineering environment , where tools like GitHub Copilot and Windsurf, Claude are used to accelerate development — with a strong expectation that you validate, refine, and productionize outputs to meet the security by design with enterprise-grade standards .

Key Responsibilities Full Stack Development Design and build scalable microservices using Java, Spring Boot, and REST APIs

Define clear API contracts (OpenAPI/Swagger) with consistent error handling and versioning

Implement event-driven architectures using Kafka or equivalent messaging systems

Build high-performance data access layers using JPA/Hibernate and Oracle/Postgres

Develop and enhance UI components using React.js and TypeScript

Build integration layers and admin UIs to support backend workflows

Ensure end-to-end flow validation (UI → API → DB → events)

Ensure production-grade reliability: transaction safety, idempotency, and error recovery

AI-First Engineering Mindset (Critical) Actively use AI tools (e.g., GitHub Copilot, Windsurf, Claude or any other Mckesson approved tools) to:

Accelerate coding, refactoring, and test generation

Improve developer productivity without compromising maintainability

Critically evaluate AI-generated code for:

Correctness and edge cases

Security and data handling risks

Performance and scalability

Apply AI responsibly in:

Code generation, debugging, and clear documentation

Unit Test case creation and coverage improvement

Design systems that are:

AI-friendly (clear APIs, structured data, consistent contracts)

Observable and diagnosable using logs, metrics, and traces

Security by design

Engineering Quality & Delivery Write clean, maintainable, well-tested code (unit + integration tests)

Participate in code reviews, design discussions, and architecture decisions

Work in Agile teams with strong accountability & ownership of delivery

Diagnose and resolve production issues using observability tools, such as Dynatrace

Platform & System Thinking Build services that are:

Reusable

Well-documented

Easy for other products to integrate

Follow best practices in:

API design

Microservices architecture

CI/CD and DevOps pipelines

Minimum Requirement Degree or equivalent relevant experience.

Must-Have Skills 4 – 7 years of software development experience in product/enterprise environments

Strong hands-on experience with:

Java (17+) and Spring Boot

REST API design and microservices architecture

Experience with React.js + TypeScript (at least 1-2 years)

Solid experience with:

SQL and relational databases (Oracle/Postgres)

ORM tools (Hibernate/JPA)

Experience with:

Event-driven systems (Kafka or similar)

Caching (Redis or similar)

CI/CD pipelines and Git-based workflows

Automated testing practices

Strong debugging and production issue analysis skills

AI-First Expectations (Non-Negotiable) Candidates must demonstrate: Practical use of AI coding assistants in development workflow

Ability to review, validate, and production-harden AI-generated code

Understanding that:

AI accelerates development

Engineers are still accountable for design, correctness, and quality

If someone blindly copies Copilot output, this role is not for them .

Foundational Clear written and verbal communication — ability to document services and explain technical decisions

Good-to-Have Skills Healthcare domain experience

Familiarity with:

FHIR / HL7 / C-CDA standards

HIPAA compliance and PHI/PII handling

Experience with:

Databricks / data pipelines

Elasticsearch / Redis

Docker / Kubernetes

What Success Looks Like Deliver production-ready features end-to-end , not just code

Build systems that are scalable, observable, and reusable

Improve team productivity using AI without degrading quality

Contribute to raising engineering standards across the team

Why This Role Stands Out Work on real-world healthcare systems impacting patient outcomes

Exposure to modern architecture + AI-driven engineering practices

Opportunity to build platform-grade services used across multiple teams
